LOUIS BLESSING, OF JACKSON, MICHIGAN.

RAILWAY-TIE.

To all whom t may concern.'

Be it known that I, Louis BLnssrNG, a citizen of the United States of America, re siding at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Railway-Ties, of which the following is a speciication, reference being had therein to the accompanying drawings.

This invention relates to railroad ties, and more especially to that class thereof which are made of concrete or cement, and in which metallic brace-rods and strengtheningl members are employed to give to the tie the desired rigidity, and it has for its object an improved organization of the strengthening members which latter are so distributed within the tie-body as to strengthen the same laterally as well as vertically, and also to give a continuous brace-support thereto from one end to the other.

The invention has been clearly illustrated in the accompanying drawings, in which similar characters denote similar parts, and in which- Figure 1 represents a top view of a railroad tie einb i dying my invention; Fig. 2 is a longitudinal vertical section thereof on lines 2 2 and also 2-2 of Fig. 1; Fig. 3 is a longitudinal section of a tie illustrating a modification.

Briefly stated, my present invention constitutes an improvement on that described and claimed in United States Letters Patent No. 873,292 granted to me on December 10, 1907, and in which the body of the tie had embedded therein a series of overlapping loo-ps of reinforcing members or wires. In my present invention I employ comparatively rigid bars extending longitudinally of the tie substantially from end to end thereof, some of these bars being shaped into truss-like members. By the present construction I am enabled to produce not only a stronger tie than before, and to save considerable weight of metal besides gaining in .the labor required to set the tie meinbers in the mold in which the plastic mass is formed.

Specification of Letters Patent.

Application flied March 18, 1911.

Patented Aug. 26,1913. serial No. 615,187.

Referring to the drawings, the preferred form is illustrated in Figs. land 2 in which the cement tie body is reinforced by three braces 10, 11, l2, which are preferably made of twisted square rods. Cushion plates for supporting the rails may be employed if desired, and the other braces are bent or shaped to form tension-rods l having their seat t or rail-support directly below the rails (see Fig. 2) from which points they rise so as to form in the longitudinal center of the tie a bridge or truss-support b. In order to preserve the stability of this brace member, as a whole, a straight rod as 10, 1l or 12 is disposed above the truss-rod, and its ends are bent over, as at 14, so that they may act in conjunction with the outer ends of the rod and hold the saine against flattening or straightening out.

In Fig. 3 I have illustrated a modication of the structure, the only difference be ing the addition of a longitudinal tie rod 20, extending from end to end of the tie and across the arch points of the truss-rods 10 respectively.

It is to be understood that the number of the trusses, braces, and tie-rods may be varied, ad lib/mm, and also that bars or rods of diiferent kinds may be employed in lieu of those shown and described, without departing from the spirit of the invention.

I claim:

A railroad tie of cement or the like, comprising a longitudinal tension rod bent to have its lower-most points directly beneath the rail supporting portions and having .its adjacent parts bent upwardly to form a. truss between said portions, and an independent tie rod resting upon said truss-rod between the rail supports and having hook ends directly hooked over and engaging the upturned ends of said truss-rod and in engagement therewith.

In testimony whereof I atlix my signature in presence of two witnesses.

LOUIS BLESSING.
